Officials suspect the foundations were not suitable for extra floors to be added to the building

Mr Joshua’s preaching is popular and his sermons are sold around the world

On Tuesday, however, a rescue official said the likeliest cause of the building’s collapse was the construction of additional storeys without reinforcing the foundations.

‘Hostile to rescuers’

At least 130 people, including many foreigners, were pulled out of the rubble.

Officials says members of the church at first prevented emergency workers from participating in the rescue.

“For the first three days of the incident, the church people were very hostile and prevented rescue officials’ access to the site,” a spokesman for Nigeria’s National Emergency Management Authority (Nema), Ibrahim Farinloyeh, told the AFP news agency.

BBC’s Pumza Fihlani in Johannesburg:

OR Tambo International Airport in Johannesburg is crowded with people awaiting the return of their loved ones from Nigeria. So far one plane has returned.

It is understood that about 300 people, not all South African, travelled from South Africa last week to Lagos for one of Mr Joshua’s healing gatherings.

The lack of information from Nigeria has not helped anxious relatives. The South African government has now set up a phone number for people to call for assistance, because some had been contacting the Pretoria embassy and phoning into local radio stations with the names of family members who had travelled to Nigeria.

Charismatic churches are hugely popular in South Africa, with Nigerian Pentecostals striking a particular chord. Thousands of TB Joshua’s followers wait in queues, sometimes overnight, to catch a glimpse of the “Prophet” when he visits. He packs out stadiums on his tours.

It is believed that at least five South African church tour groups were visiting the church at the time of the collapse.

“This is a particularly difficult time for South Africa. Not in the recent history of our country have we had this large number of our people die in one incident outside the country,” Mr Zuma said in a statement.

“Our thoughts are with the families, friends and colleagues that have lost their loved ones in this heart-breaking tragedy. The whole nation shares the pain of the mothers, fathers, daughters and sons who have lost their loved ones. We are all in grief.”

Following the collapse, Mr Joshua has continued to post scriptures on social networking sites to his hundreds of thousands of followers.

Known as the “Prophet”, he regularly preaches to large crowds at a mega-church in Lagos’s Ikotun district.

His followers in Nigeria and abroad believe he has the gifts of healing and prophecy.
